The analysis of the effect of micronized pyroclastic rock addition to red mud directed at the sustainable buildin material production

Approximately 40% of the material used in the process of obtaining aluminum from the bauxite is left as waste to the environment. Storage ponds were made for this waste material called red mud. Wastes accumulated in ponds can become an environmental disaster with the potential danger they generate. With the use of waste material, this danger will be eliminated. The aim of this study is to investigate the usability of waste in the construction sector as a baked building material. In addition to have been using of waste by itself, pyroclastic rock addition to waste was also thought as a contribution to its properties. For this purpose, different areas which are abandoned are selected. Thus, it will be possible to use both the waste and the raw materials obtained from the inert pyroclastic fields. In this way, the study will contribute to the concepts of sustainable environment, structure and material. In this study, the effects of micronized pyroclastic rock addition to red mud were investigated. For this, 10%, 20, 30, 40, 50% micronized pyroclastic rock was added to the red mud in the preliminary experiments section. Samples prepared according to the mixing ratios were baked at 930, 1000 and 1050 oC. In the section of preliminary experiments, reducing ratios of volume and compressive strength values were determined. Thus, optimum mixing ratio and temperature degree baked have been determined. Physical, mechanical and chemical experiments were performed to determine the general properties of the samples, which has optimum values. As a result, it has been observed that a sustainable modern building material can be produced by the addition of micronized pyroclastic rock to red mud.
